Abstract
A method for determining the quantity of fuel flowing through a fuel injector. The fuel injector has an electric heating device for heating the fuel and a temperature-measuring device for measuring the temperature of the heated fuel. The method includes (a) applying a predetermined electrical heating power to the electric heating device, (b) measuring an increase in the temperature of the fuel as a consequence of the heating power, and (c) determining the quantity of fuel flowing through the fuel injector on the basis of the applied electrical heating power and the measured increase in the temperature. A method for equalizing the fuel feed at at least two cylinders of an internal combustion engine utilizes the method for determining the quantity of fuel flowing through a fuel injector. An engine controller and a computer program carry out the specified methods.
